Kevin and Julia Dawn Garratt, accused of spying in China, held in near isolation, son says

A Canadian couple accused of spying near China's sensitive border with North Korea has been kept in near isolation for more than 80 days, their son said, and they have repeatedly been denied access to legal counsel.

Treatment of the couple, who are being held without charge at a remote facility in the border city of Dandong, has seriously strained China's ties with Canada ahead of a planned visit by Canadian Prime Minister Stephen Harper for a multilateral summit next month in Beijing.

Kevin and Julia Garratt were allowed to meet briefly for breakfast last week - the first contact they had with each other during their detention.

"It's not their physical health I'm concerned about, it's more their mental health," said their son Simeon Garratt. "You put anybody in a situation like that for 80 days, where you can't talk to anybody else and with no outside contact, and you don't know what could happen. It's not about food or water."

No formal charges laid

The Vancouver couple had opened a cafe called Peter's Coffee House in Dandong in 2008. State media has reported they are suspected of stealing national security secrets, but no formal charges have been made and it is unclear what exactly they are accused of.

Kevin Garratt told a congregation in Canada last year that he ran a prayer and training facility frequented by North Koreans, many of whom became Christians before returning to the isolated country.

Hundreds of Christian aid workers near the North Korean border have been detained or forced to leave in a crackdown this year.

Both Kevin and Julia are under 24-hour surveillance by two guards. Canadian consular officials visit with them every two weeks, Simeon Garratt said. They are frequently interrogated, he said, though the subject of the questions is unknown.

"Their daily routine is to wake up, have breakfast and wait to find out whether they'll be interrogated that day or not," he said.

The Garratts' children communicate with their parents through written letters sent through Canadian consular officials. But not all of them get through. A coffee-maker and other supplies sent by the Garratt's younger son was also never delivered.

Requests for access denied

Authorities have repeatedly denied the family's requests for access to legal counsel since the Garratts were detained August 4, according to a source with direct knowledge of the matter.

The source added that authorities had said re-applying would almost certainly be fruitless.

"They remain detained and isolated from their family and legal counsel, and in conditions that are nothing short of demeaning and withdrawn from meaningful human contact," the person said. "Under such circumstances, any human being under the pressure of isolation could easily incriminate themselves."

The Canadian Embassy in Beijing could not be immediately reached for comment.

It is unusual for foreigners to be charged with violating China's state secrets law - a serious crime that is punishable by life in prison or death in the most severe cases.

In September, Canada ratified a foreign investment protection agreement with China after a two-year delay in a move that could help ease tensions with China.
